HYROCARBON-BURNER.

YBPECIFICATXCN 'forming part of Letters Patent No. 388,988, dated September il, 1858.

Application filed September 16, 1837.

'o all whom zit may concern.-

Be it known that I, SAMUEL MOMURRY, of Alameda, Alameda county, State of California, have invented an Improvement in Hydrocarbon-Burners, and I hereby declare the following to be a lull, clear, and exact description of the same.

My invention relates to that class of devices for burning liquid hydrocarbon in which the parts are so arranged as to provide for a union of theh yd rocarbon with airandsteaimwhereby it is atomizcd or vaporized; and my invention consists of such an arrangement of parts as will provide for the introduction and union, with the hydrocarbon in a heated state, of the air, also in a heated state, and superheated steam, all of which, together' with details of construction, I shall hereinafter fully describe.

The object of my invention is to provide for the most com plete and perfect atomizing or vaporizing of the liquid hydrocarbon, and this is attained by the union of the hydrocarbon and air, both in a heated state, with snperheated steam.

Referring to the accompanying drawings for a more complete explanation of my invention, Figure l is a perspective view of my burner, showing it in position. fFig. 2 is a section of the burner.

In order to fully illustrate my burner,l have herein shown it in connection with a boiler, A, of which B is the lire-box.

The burner proper, which lies within the fire-box, consists of a pipe, C, shown in two sections, coupled at c, so as to leave an opening between them for the introduction of the air, as will presently be explained. One of the sections of the pipe C is coupled at c to the oil-feeding device, which i shall hereinafter describe.

Around the forward section of the pipe C is fitted a pipe, D, having a diameter enough larger than the pipe C to leave au annular space between them, said space being closed at its forward end and having a coupling at d, where the pipe d joins it, said pipe extending upwardly to the upper portion of the flrebox B for the purpose of drawing from said box the air which is heated to the highest temperature. The other end of the pipe is also closed, but has a pipe, di, connecting its inclosed space Serial No. 319.SR3. (No model.)

with the space at c between the sections of the pipe C.

E is a pipe which extends through the pipe C to a point short of its forward end. The pipe E has a diameter sufficiently small to leave a space between its outer surface and the inner surface of the pipe C, as shown, and the rear end of said pipe E is connected by a pipe, e, with the steam-boiler.

The means for feeding the oil, and which extends in front of the lire-box, consists of a pipe, F, connectedat one end with the oiLreservoir (unnecessary herein to show) and at the other end at o with the pipe C, the com munica tion being controlled by a valve, f. The pipe F is provided with an enlargement forming a chamber, G,having a downward extension and an outlet controlled by a cock, g.

Around the rear of the pipe Fis fitted a larger pipe, H, providing for a space between itself and the pipe F, said space having a communication at L with a pipe, I, from the boiler, and an outlet controlled by a cock, t'.

The operation of the burner is as follows: The oil is first passed from the reservoir into the pipe F, wherein its temperature is raised by means of steam admitted from the boiler through the pipe l intothe space inclosed by the pipe H, and the water of condensation from said steam is drawn off through the cock t'. The oil fills the enlarged chamber G of the pipe F, and the water which may be contained in it, sinking to the bottom of said chamber, is drawn ofi' through the cock g. The oil new passcaits 119W being regulated by the valve f, into the pipe C'oithe burner, and iiows forward in said pipe. ot airis drawn from the upper portion of the iirebox down through the pipe d and is admitted to the Vspace inclosed by the pipe D of the burner, whence it passes backwardly through the connectingpipe d? and enters the pipe C, joining the oil in a highly-heated condition, and passes forward with said oil. Steam is admitted from the boiler through the pipe c and passes into the pipe E, whence, blowing forward into said pipe, it is ejected from its forward end, meet ing at that point and within the burner proper the heated air and heated oil. The oil is now vaporized and atomized, and, being ignited, the burner itself soon becomes red hot and the ICO steam passing into it becomes superheated, so that the oil7 the air, and the steam all operate under a high temperature. In this burner it will be seen that the discharge end is en- 5 tirelyopen and untrammeled by any valve, so

that heavy oils can be used With success, and the fact of bringing the air, the steam, and the oil together in a highly-heated condition adds to the usefulness of the burner in using all Io Weights of oils.

I5 conveying oil and communicating at its rear end with the oil-supply, and the pipe E for steam, communicating with the boiler, said pipe being fitted within the pipe C and ter- Initiating short of its forward end, in combina- 2o tion with the pipe D, encircling the pipe C,

the vertical pipe d', communicating with the forward end of the pipe I), and apipe, d'2, connecting the rear end of the pipe D with the oil-pipe C at a point back of the forward end of the steam-pipe, substantially as herein described.

2. In a hydrocarbon-burner, the concentric pipes E, C, and D,for the steam, oil, and air, respectively, said pipes communicating, as dcscribed, in combination with the pipe F, for supplying oil to the pipe C, the chamber G in said pipe F, and the cock g, controlling said chamber, whereby the water in the oil is allowed to settle and may be drawn off, and the encircling steamjacket H, having a cock, t', whereby the Water of condensation may be drawn off, substantially as herein described.

In witness whereof I have hereunto set my hand.

SAMUEL MCMURRY.
